Santa Barbara hiker reported missing in the Sierra

FRESNO, Calif. 
Authorities are searching for a backpacker who has been reported missing in the Sierra Nevada.

The Fresno County Sheriff's Office said Monday that search and rescue teams had been deployed to find Adam Thomas Johnston.

The 21-year-old from Santa Barbara was reported missing Sunday night by his family. He had been hiking with his father and a friend near the Humphreys Lake Area.

The hikers split up last Thursday after a couple of days of backpacking, but had agreed to meet up later at a specific location. When Johnston didn't show up, the other hikers returned to their starting point in Bishop and reported Johnston lost.

Teams from Fresno and Inyo counties are looking for Johnston, who had provisions for about five days.
